Abstract:
An almond breeding program was initiated in 1966 to develop improved cultivars for arid conditions with irrigation. Nut and kernel traits were evaluated for almond parents and progenies. Highly significant parent/progeny correlation coefficients (0.7-0.9) were found for shell hardness, percentage of kernel, in-shell (nut) and kernel weight, kernel length and width, as well as kernel color and outer shell retention. Double kernels and kernel thickness had low parent/progeny correlation coefficients. Shell hardness and percent kernel were highly correlated, as were shell hardness and outer shell retention, percent kernel and outer shell retention, and kernel width and nut weight. All but two of the evaluated traits (kernel thickness and percent doubles) appear to be highly heritable with mostly additive gene action, although some degree of dominance appeared to be involved in percent kernel, shell hardness and percent doubles. © 1981 Veeman B.V., Wageningen.
